It is only February, but if this year brings a series as endearing and as poignant as One Day, well, we will be lucky indeed. Based on the novel by David Nicholls, One Day traces the arc of a friendship between two students who meet on July 15, 1988, at a college graduation party in Edinburgh. The one-night stand between Emma Morley and Dexter Mayhew is a hilarious mishap, but it produces a friendship whose arc is examined every July 15th for the next 20 years. Would One Day be this charming if it did not star Ambika Mod, who shone in This Is Going to Hurt, and Leo Woodall, who memorably played the “nephew” Jack in season two of White Lotus? Absolutely not, as the misfire 2011 movie version starring Anne Hathaway and Jim Sturgess painfully shows. The 14 episodes are short bursts of emotional adrenaline (one clocks in at 19 minutes) laced with a marvelous soundtrack (The Cranberries!) and filmed in places that are a location scout’s dream (Paris, Rome, Greece, as well as Scotland and England). One Day gladdens the heart, then splits it apart, proving in the end the healing powers of memory. —Jim Kelly
